“…In same year Ciana et al disclosed Friedel-Craft-type Cu-catalyzed paraselective arylation of electron rich phenol ethers alongwith secondary and tert-anilines with diaryliodonium salts (Schemes 49 and 50) (87). Excellent selectivity with good yield was observed for various oxygen bearing arenes and different diaryliodonium salts (Scheme 49).…”

“…Various functional groups were well tolerated on both coupling partners with moderate to good yield. Although excess of Pd(OAc) 2 (20 mol%) and PPh 3 (40 mol%) were used but this was first examples for the synthesis of selective 4-arylated phenols with wide substrate scope (87). aqueous media and various coordinating group such as amides, acids, as well as ketones were well tolerated at aryl iodide.…”

Distant C-H Activation/Functionalization: A New Horizon of Selectivity Beyond Proximity

Activation/functionalization of inert C-H bond has undergone rapid growth in last decade and provides novel retro-synthetic disconnections for the synthesis of valuable molecules. The selectivity is often achieved by the use of directing group and is mainly limited to the proximal C-H bond. Initially, meta C-H activations were based on electronic or steric control and now it can be achieved by employing nitrile-based end-on-template as the directing group. The compilation of the remote C-H activation strategy will provide the useful linkage to the scientific community. This article is focused on recent progress in remote C-H activation, mechanistic understanding, and its applications in the field of total synthesis of targeted molecules.

Recent Advances in Copper-mediated Direct Biaryl Coupling

2015

View full text Add to dashboard Cite

Copper salts and complexes have recently received significant attention as less expensive, abundant, and unique alternatives to noble transition-metal catalysts such as palladium, rhodium, and ruthenium, in the research field of C–H activation. This highlight review focuses on recent advances in copper-mediated biaryl coupling via aromatic C–H cleavage, and the scope and limitations are briefly summarized.

“…Diaryliodonium salts have recently been recognized as versatile reagents in organic synthesis. 2 They can be employed both in metal mediated and metal-free reactions thereby avoiding the potential drawbacks of organometallic chemistry such as toxicity and high cost. 3 Efficient one-pot procedures to diaryliodonium salts have been developed within our group (Scheme 1) increasing the availability of these compounds.…”
